Add cross-repository workflow integration and connectivity

[Copilot]

Enhances GitHub Actions workflows to monitor and coordinate with related repositories (Web3AI, gatsby-starter-blog, Time-Machines-Builders-, AI-Time-Machines).

Workflow Enhancements

CI Workflow (.github/workflows/blank.yml)

• Manual dispatch with repository selection dropdown
• Repository dispatch trigger for accepting events from other repos
• Matrix job to monitor connectivity with all linked repositories
• Displays connection status on each run

Cross-Repository Sync (.github/workflows/cross-repo-sync.yml)

• Visual network topology display
• Matrix-based notification system for all connected repos
• Prepared for PAT-based repository_dispatch (commented with setup instructions)

Documentation

• README.md: Links to connected repos, workflow badges, usage instructions
• REPOSITORY_NETWORK.md: Network diagram, advanced setup, troubleshooting

Usage

Manual trigger with repository selection:

workflow_dispatch:
  inputs:
    target_repo:
      type: choice
      options:
        - 'Web3AI'
        - 'gatsby-starter-blog'
        - 'Time-Machines-Builders-'
        - 'AI-Time-Machines'

To enable actual cross-repo triggering, add REPO_ACCESS_TOKEN secret and uncomment the repository_dispatch step in cross-repo-sync.yml.

Security

• Explicit permissions: contents: read on all jobs
• CodeQL scan: 0 alerts
